New Dataset RuntimeError: dtypes match error.

[RichardShea]

Hi,

When trying to run a new dataset, I match the datatype exactly as the climate datatype. The new dataset are timestamps generated from a Hawkes process. Below is the error.

Thank you,

Hi @RichardShea! I am not sure if using the same setup as the climate dataset is directly applicable on a new dataset. Maybe try adding print statements to debug which dtype is incorrect?
